Tortilla Soup 2

Tortilla soup or Sopa Azteca as it is also known, gets its name from the thin strips of fried tortillas strips that are added just before it's served. Traditionally, soups in Mexico have been used by the masses as a way to stretch an ingredient as far as possible. Sopa Azteca, it is believed, was created at least partially as a way to use up leftover stale tortillas.
